Help with Challenge #2. Message "Does Increment have a constructor that takes no parameters?"

I'm getting the above message when I Check my code. { abstract class Increment : IUnaryOperation { public Increment() {}

    public virtual double Perform(double value)
    {
        return value += 1;
    }
}

}

The instructions didn't ask for the new class to be abstract.

Also, you don't need an explicit constructor if you don't do anything different from what the system assumes by default (no arguments, no code body).

Also, the abstract and virtual modifiers are not needed.
